Abstract

Phenolic compounds extracted from cactus seed oil were identified for the first time by HPLC-ESI-qToF-MS and subsequently quantified by HPLC-DAD. A total of 7 compounds were identified, vanillin, syringaldehyde, and ferulaldehyde were found to be the most abundant ones. The effect of geographical origin and roasting process of cactus seeds was evaluated. Differences between different locations were not found, however the roasting process had a significant effect on the amount of phenolic compounds. The amount of syringaldehyde, p-coumaric acid, p-coumaric acid ethyl ester, and ferulaldehyde increased during the roasting process. Nevertheless, the concentration of vanillin was not influenced by roasting. It was demonstrated that the increase of those compounds was due to the thermal degradation of lignin from the seeds during the roasting process of seeds.

Highlights

Cactus (Opuntia ficus-indica) is a robust plant belonging to the family Cactaceae, originally coming from the arid and semi-arid areas of Mexico
It is necessary to know more about the composition of phenolic compounds in cactus seed oil
During the last decade, growing interest in Opuntia ficus-indica has resulted in a large number of scientific papers

Summary

Introduction

Cactus (Opuntia ficus-indica) is a robust plant belonging to the family Cactaceae, originally coming from the arid and semi-arid areas of Mexico. In Morocco, especially in areas with limited access to water, the cultivation of cactus plants can play an important role because it is a suitable species for sustainable agriculture and can help to protect the soil against erosion and to fight against the spread of the desert, slows down the decline of fertile soil, and ensures biodiversity. Mainly cactus fruits, called prickly pears, have become very popular for different purposes such as foods, cosmetics, and pharmaceuticals. This generates an income for farmers and local persons in rural areas of Morocco and plays an important socio-economic role and contributes to a sustainable development in rural areas
